Lit all 07mm it may concern} e 7 Be it known that I, WADE H. E ulnoii',a citizen of the United States, resldlng at Windy, in the county ofWirt,\S tateof West Virginia, have invented certain new and usefulImprovements in Explosive-Engines; andI do hereby declare thefollowingto be a full, clear, andexact description ofthe in- ,vention,such as will enable others skilled n the art to which it appertains tomake and use the'same. p e i @This invention relates toimprovements inexplosive engines.

The principal object of provide an explosive engine of thattype in whichexplosions alternately occur at either end of the piston upon every twosuccessive revolutions. j a Another object of the invention is toprovide a novel. timing mechanism for the sparking means whereby theexplosive min ture .inthe 1 opposite ends of the cyl nder will bealternately fired. w

Anothe object of the invention is to provide a novel means for; cuttingout the explosive' mi iturefrom either end of the cylinder wheneverit isdesired toemploy the en gine for alight load. p p I e e A further objectof the invention. is to provide an engine of the. character describedwhichis extremely simple ineonstruction, it being composed of a minimumnumber of parts, end isthereforecheap to manufacture. e

. Withthese and other Objects in view, the

invention consists in the construction-and novel combination of partshereinafter fully described, illustrated in the accompanying drawingsandpointedout inthe claim here- I to appended; it being understoodthatvarious changes in the form, proportion, sine 5 and minor ClGtaIlS ofconstruct on Wltllll l the scope of, the claim' may be resorted towithout departing from the spirit or sacrificing any of the advantagesof theinvention'. In. the drawings:

Referringto the drawings, my invention: comprises a base 5, andthis baseincludes cross head guide 6 anda crank case 7. Suit-1 ably mounteduponflthe base 5 in alinement withthe cross head guide 6 is ahorizontally disposed .cylinder 8 in which is slidably mounted a piston9. A piston rod 10 isconnected to the piston 9. and extends through asuitable boxing :12..intothe guide 6, and. the [end of this rod isconnected to a suit able cross head 11 which in turnjis connectedto apitman 12 that is connected to. a crank 13 of a crank shaft 14, saidshaft being suitably supported upon the base 5..and in the crank case7.1.Fly-Wheels shaft 14.

Securedto the opposite ends of the cylinder. 8 and offset from onesidethereof are valve {chambers 16+16 which respectively communicate withtheends of the cylinder 8 through exhaust/ports 17. Each chamber includes avalve seat 18 which isnormally closedby a valvelt) mounted upon a vertiwcal stem 20, the lower end thereof projecting below the chamber 16 andhaving a nut QL fi Xed thereon. A coil spring 22 is dis-. posedaroundeach stem 20 between the chamber 16 and the nut 21 for yieldablyholding thevalve 19 upon its seatlS. An exhaust pipe 23 has its endsconnected to thevalve chamberflG at points below the valveseat 18,andthisipipe is centrally con means of suitable gearing 27. Depending fromthe cylinder 8 and 1n alinement with.

each exhaust pert 17 is a pairof spaced cars jacent each end thereof areinlet ports- '32''32, and these ports connect with a main intake pipe 33through the medium of branch pipes 34 -34Y I iocated in each branch pipe34 is ax'check-valve 35 of any suitable 'construction,"an d located inthe main intake pipe 33 is a check valve 3(3 of any suitableconstruction. The main intake pipe 33 reconnected to one end'of a pump37 which is supported upon the base 5 and includes theusual'pistoii 3Sand piston rod "39, the latter being connected,to a pitman 40' which "isoperated by an eccentric 41 mounted on the crankshaft 14. The intake endof the pump '37 is connected with p a pipe 42' which leads'from anysuitable source of gas or'gaspnne; f

iliornied} in each end .43 f thecyIinderB is an opening'44, and securedto 'theouter face of each end 43" emanate respective opening44 is aplate45', and inlthis plate is journaleda rock shaft 46 'vvhich,ca'r1fies acontact "fi-ji'iger- 47 'vvhich engages with and disengages from a fixedcontact48. A wire 49 is connected to thefing'er'4 7 and a wire 50 isco'nneoted tothe finger 48,th'ese wiresbeing suitably connected to anysource of electrical energy and a sparks-011 (not shown) This finger-"isyieldably held out of engage-. ment with the eontact'point48 by meansofa spring 51 and extending from the finger is a'projection 52.Eulcrumedintermediate their'en'ds, as at 53,upon a respective,'end 43of; the cylinder 8 are'trip levers5 4, one end" ofeach' lever engaging arespective piojectioh "52 the other end being,

engaged 'Tres'pective cam 55 which is mounted upon the cam shaft 26,said m I' s a rna e y d p sed so a to actuate the ,trip'levers 54alternately.

W-hen each trip lever 54 is actuated, theprojection "5 2 iselevated, andasa result, the contact finger 47 will engage thehcontact poin 4.8. Assoon a the-M11155 be ome disen a ed from the lever, thespring 51swingsnie contact finger 47 awa "from the, coiitact'point48, gtherebycreates a spark. for explodi-iig 'the mixture Within that, end erascylinder;

order to retain either of thevalves 1.9.

, Pfi le t jsir sple s n as id .the cylinder- 8. The head includesoppositely extending arms 5959, and these arms are Vadaptedto engageeither of the rock levers 30, as will be hereinafter explained. Inordertolock the lever 30 in any adjusted po sition so as to retainarespective rock lever 30 in its inoperative position, the upper end ofthe lever engages over a plate 60 which is carried byv the cylinder 8;This plate is formed with three spaced openings 61 and a pin 62ciarriedby the leveris adaptedto engage in any one of the openings 61.

In the operation of this engine,assun in the lever 56 to be its neutralposition an consequentlyout of engagement with either rock lever 30, therotation of the crank shaft 14 will slidethehottom 9 toward one end ofthe cylinder, and atthe same time actuate the pump 37 to draw-inaquantity of explosive mixture through the pipe 42.

This pump will then -force this mixture through the pipe 37 tothe mainintake pipe 33 and the piston 9 will by suction open ne ofi he valv 35 1M 6 lve 6 th r by drawing the mixture into that end of the in r hfl thePi$ 11i$ r turn n to compress this charge, a second charge is beingdrawn into the other end of der." -lVhen the piston has reached itslimit of movement, the cam 55 at that of the camshaft 26 will actuatethe centact finger 471to closethe spark circuit, and as a result, x lodethe, m xt r in t a nd f the y in'der. Immediately following thisexplosion, the respective cam-3 l will actuate the respective rock lever30, and thereby unseat the valve, 19 to perinit ofthe exhaust gasespassing out through the exhaust port 17 through the pipe 23 .to the man. exhaust pipe This operation is of course repeated at the. other endof the cylinder,

During this operation a predetermined quantity of air is" admitted tothe pipes 34 through openings 34, said openings being controlledrespectively by needle valve, 35 when it is desired to explode themixture inoneend of the cylindeig onlythe lever 56 is e ked r nful r m.58 an a arm 62 is engaged within one Of the outer. openings 61 .of theplate, This lever will thus be held'in its adjusted position, and asaresult, the rock lever 3Ov will be depressed downwardly andconsequently out of engagement with its respective cam 31 a result, thevalve 19 will be retained in its raised posiio an eq n l en h nisten *9;moves from that end of the cylinder, no suction will take placesu-iiieient to unseat the respective valve 35 and the valve 36; As aresult, no mixtnre. will: be drawn into this end of the cylinder. It isobviousthat in this operation a surplus of fuel would be supplied, butthis excess fuel supply may be compensated for by any of a number ofdevices well known in the art, no specific device being shown.

What is claimed is:

In an explosive engine, the combination with a cylinder having inlet andexhaust ports respectively formed in either end thereof, of a crankshaft, a piston slidable in the cylinder and operatively connected tosaid shaft, spring actuated valves including valve stems normallyclosing the exhaust ports, rock levers each fulcrumed on the cylinderand having one end engaged with a respective valve stem, means actuatedby the crank shaft for alternately actuating said levers to unseat thevalves, means engageeeplea or We patent may be obtained for able withsaid levers for locking either valve opening, said means consisting of aT- shaped lever comprising'a leg and oppositely extending arms, the legbeing fulcrumed upon the cylinder intermediate its ends and the armsbeing disposed in operative proximity to the levers, and means carriedby the lever and engageable with the cylinder for locking saidlever inits intermediate or either of its adjusted positions.

In testimony whereof, I aifix my signature, in presence of twowitnesses.
